When I first access your video, I see this:

This is just while it is pre-buffering ...
Shortly after, it resizes and starts playing, and I see this:
VERY nice gallery by the way. I have a few quick suggestions:
# For your video page, since you only have a single video, you may want to skip displaying the thumbnail and go directly to the video. This can be achieved with folder parameters:

Set this in your
folder parameters, for this folder:
# You have some nice pictures on the startpage. Unfortunately, the startpage filemod does not scale images down to fit smaller screens. Perhaps you should consider using the slideshow by folder-parameters instead. Then it will scale down images to fit the visitors screen if necessary.

(Scroll down to examples -> slideshow, and see the code)
# You could perhaps add all your photo folders under a main category [+] Portfolio at the top of the menu. This would make the menu a bit clearer and not so long, but still stand out with the darker text. Just a suggestion from my side.
This gallery would easily be new featured gallery of the week if you want to add it to our list:
